OPTICAL TOY.

SPECIFICATION forming part of Letters Patent No. 694,967, dated March11, 1902.

Application filed June 1'7, 1901. Serial No. 64,897. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM JINKINGS, .a subject of the King of GreatBritain, residing at 49 Gladsmuir road,Highgate, London, England, haveinvented Improvements in Optical Toys, (for which I have applied for apatent in Great Britain, No. 21,577, bearing date November 29, 1900,) ofwhich the following is a specification.

My invention consists of a toy tent, preferably of the pointed orconical shape, within which at one side of the opening is fitted a pieceof silvered glass. The glass in the case of a conical tent occupies thespace, triangular in shape, between the center-pole, the outer covering,and the base on which the tent stands. A secret space is thus formed,into whicha toy figure, such as a soldier, working on a pivot,controlled, preferably, bya spring, is made to disappear and from whichit may be made to reappear at will. I attain these objects by themechanism illustrated in the accompanying drawings, in which- Figure 1is an elevation, Fig. 2 is a plan, Fig. 3 is a side elevation, of glassand mechanism.

B is a base with a slight ridge round edges at bottom to form a hollowspace in center.

Upon this base is placed a triangular piece of silvered glass 0, theperpendicular side of which is fixed at about the center of said base.

A covering A is fixed to the front edge of glass at P and carried roundto Q, is fastened to base B and also to apex of glass at N, thus leavingan opening in front. Upon the per- In the rear of glass 0 is fixed ablock E, through which a pivot F is carried, which extends through baseB, having its end bent at right angles F. The upper end of this pivot iscurved round and attached at K to the figure of a soldier D." A portionL is cut out of block E for the purpose of holding pivot Fin positionwhen pulled down- A pin J is fixed to block E to hold pivot F in itsnormal position. To pin H is attached a rubber band G, which is fastenedat its other end to figure D.

The toy is thus operated: By turning the pivot F by its bent endF' thefigure D is brought round from behind the glass to the front and isreflected in said glass, as shown at D, thus giving the appearance oftwo sol= diers in the tent. By pulling down the pivot F at 13" it iskept in position by cut-out por tion L. On pressing down the apex of thetent at N pivot F is pushed up in consequence of F'coming into contactwith the surface upon which the tent stands, and the figure D is swiftlycarried back to its normal position by the tension of the rubber band G,dotted lines M and M showing this movement.

Having fully described my invention, what I claim, and desire to secureby Letters Pat out, is-

The combination of a silvered glass C, with block E, pivot J, spring G,lever F, and figure D, substantially as described and shown.

WILLIAM JINKINGS.
